Abstract

This invention provides support structures on roofs. Such support structure can be used to support a roof load, or a closure structure which closes an aperture in the roof, thus to provide access to the interior of a building through an aperture in the roof. The support structure can support a skylight to provide natural day-lighting, or a smoke vent, or a variety of other loads optionally relating to matter or energy communication between the inside and outside of the building. The support structure includes rails adapted to be supported by adjacent rib elevations on opposite sides of a flat of a roof panel, elevated above the water line of the panel flat. Where the support structure surrounds an aperture, a diverter seals a cut away portion of the rib structure and diverts water through the rib structure and laterally away from the rail and closure structure.
